Non-Linear Optical Receiver

Abstract

A method and apparatus for optical communication. A plurality of optical signals having a plurality of different frequencies is received at a receiver. The plurality of optical signals received at the receiver is sent through a non-linear optical element in the receiver such that a resulting optical signal is generated that has a frequency based on at least one of the plurality of different frequencies. Information is identified in the resulting optical signal.

Description

BACKGROUND INFORMATION[0001]1. Field:[0002]The present disclosure relates generally to optical communications and, in particular, to transmitting information. Still more particularly, the present disclosure relates to a method and apparatus for transmitting information from multiple optical sources.[0003]2. Background:[0004]When transmitting information, different environments may be better suited than other environments for use of different components in a communications system. For example, with optical communications, a transmitter for optical signals may perform better in one type of environment than a receiver of the optical signal. As a result, in some environments, the transmitter may be able to transmit optical signals with a desired quality over greater distances. However, the receiver may be unable to detect the optical signal as well as desired in that particular environment.[0005]For example, other optical signals may be present in the environment other than the optical ...

AI Technical Summary

Benefits of technology

The patent describes a method and apparatus for optical communication. The system receives multiple optical signals with different frequencies and sends them through a non-linear optical element in the receiver. This results in a new signal with a different frequency that contains information from the original signals. This technology allows for faster data transmission and improved optical communication.

Problems solved by technology

However, the receiver may be unable to detect the optical signal as well as desired in that particular environment.

The receiver may have difficulty detecting the transmitted optical signal with other optical signals being present in the environment.

Thus, detection of the desired optical signal may be more difficult than desired.

Depending on the environment, identifying the signal may be more challenging than desired even with currently used techniques for identifying optical signals.
